ASTM A213 Alloy Steel Pipe
American Society for Testing and Materials (ASTM) A213 is a widely recognized standard that specifies seamless ferritic and austenitic steel tubes used in high-temperature applications such as boilers, superheaters, and heat exchangers. This standard includes various grades like T5, TP304, and others, with some grades marked with an "H" to indicate enhanced creep rupture strength compared to their non-H counterparts. ASME SA213 pipes are specifically chromium-molybdenum steels containing alloying elements that improve their performance under extreme conditions.
CSC STEEL is a leading manufacturer and supplier of ASTM A213 low alloy steel pipes available in multiple grades and sizes. We offer a wide range of seamless pipes, including T2, T11, T12, T22, T91, and T92, in various finishes such as annealed and pickled, bright annealed, or polished, according to customer specifications. Our products are designed to meet the demanding requirements of industrial and power generation applications.
